Employing the Yuanji Chart theory , traditional cultural heritages and modern scientific theories,It is argeud that the crux of memory improvement lies in the cohformity to the law of memory,in the exercise of the controlling function of wisdom and knowledge ,in the learning of Yuanji, and especially in enforcement of the workings of the "sound filling the universe".

It mainly includes two parts: a) to consider the theoretical constructs that underlie the role of memory from cognitive perspective,that is,memory is necessary and sufficient for successful SLA;without memory,there can be no move from input to intake;and b) to put forward some effective study methods for second language acquisition according to memory law.

This paper examines the influence of 2-month motor meta-memory training on motor meta-memory level and movement memory with non-PE university students.

Numerical simulation of the dust movement rule in fully-mechanized coal faces;

Numerical simulation analysis of the movement rules of projectile in soil;

The differential equations of three mass points are derived for different mass relations between them,and their analytic solutions are obtained,by which the movement rule of three mass points are discussed.
